WHAT'S HAPPENNING??

The East Hills are part of the mountain range located in the central area of ​​Colombian Eastern Cordillera, which runs from south to north the Capital District. This orographic has great regional importance as a geographical barrier, ecological corridor and aquifer recharge area, and is one of the main strategic ecosystems Bogota has an approximate area of ​​13,224 hectares

At the district level, East Hills offer ecosystem biodiversity, water sources and are the main ecological corridor of the city. The Biodiversityecosystem is generated by its wide altitudinal range (from 2,650 to 3,600 meters), on which a ecoclina 1 shown in vegetation of high Andean forest with presence of low, medium and high encenillales (Weinmmania tomentosa), hand extends bear (Oreopanax floribundum), Camarona grape (Macleania rupestris), among other species; subpáramo (bushland) and Paramo (pajonales, rosetales and frailejonales). These plant formations are in relictual state, ie they are small patches of vegetation extension if compared withits original cover, and are isolated from each other.

According to the Botanical Garden José Celestino Mutis, The hills are invaded by non-native tree species by about 66%, ie most of which are made up of hedges intervened with forest plantations that are changing the ecosystem and are affecting completely to this medium environment

﻿INVASION OF SPECIES

﻿

In the early twentieth century varied interventions occurred in the hills

The 1960s were characterized by reforestation with eucalyptus , cypress , acacia and other alien species such as pine.

What we mean a drastic cmbio in the characteristics and properties of the ecosystem , bilogicas varying soil compositions and making the water from the hills began to decrease and also the rest of wildlife is affected .​

FIRES

As you already know , changing ecosystem structure and soil properties , along with the invasion of drier and prone to stoke the fire , in the last years nonnative species have presented the biggest fires in the city from Bogota.

Pines and eucalyptus species are very special because they need the extreme consumption of water to survive , generating a very large dryness and generates a very dry and prone to catch fire environment. And if that will together irresponsible human activity , and the phenomenon of the child, which has generated rationing water shortage , it all adds an ecological catastrophe , as well lived in early 2016.

﻿HIDRYC THREAT

In the eastern hills of Bogota have dried up in the last century at least 40 percent of the hundreds of creeks and streams that were born there and served to drain the monumental native forest

SPECIES EXTINCTION : WILDLIFE​

With all this damage , native species like the rascal , the myrtle and other species have been disappearing for invasion of others that destroy their environment, have been lost almost 24 % of the native flora. Besides these , animal species have had to migrate , or look for a more stable means to survive , to be threatened to die , besides hunting humans, who is finishing all species as the ocelot.
